ArmCord
ArmCord is a custom client designed to enhance your Discord experience
ArmCord is a custom client designed to enhance your Discord experience while keeping everything lightweight. ArmCord is built as a standalone client and doesn't rely on the original Discord client in any way.

ArmCord natively supports theming of the entire app, you can easily import BetterDiscord themes and manage them. ArmCord automatically blocks all of Discord's trackers; even without any client mods, you can feel safe and secure! Unlike other clients, ArmCord supports rich presence (game activity) out of the box thanks to arRPC. ArmCord has experimental mobile support for phones running Linux such as the PinePhone. While this is still far from an ideal solution, we're slowly trying to improve it. ArmCord is using a newer build of Electron than the stock Discord app. This means you can have a much more stable and secure experience, along with slightly better performance. -

Session Desktop
A Decentralized, Onion Routed, Private Messenger
Session Desktop is an open-source, privacy-focused messaging application that brings secure, decentralized communication to desktop environments such as Windows, macOS, and Linux, providing users with encrypted text, media, and group chats without requiring phone numbers or email addresses. Built on the Session protocol and the Loki network, it routes messages through a distributed onion-routing network that hides metadata like sender, timing, and location so that conversations are resistant to surveillance and correlation attacks. The desktop client pairs seamlessly with Session mobile apps but can also be used independently to communicate with Session contacts in a familiar desktop interface that supports a full keyboard, global notifications, drag-and-drop media sharing, and local file access. Session emphasizes zero-knowledge privacy, meaning that only the participants in a conversation can read the messages. -

Telegram Web A
Telegram Web A, GPL v3
Telegram Web A is a full‐featured web client implementation for Telegram, built from scratch as a lightweight, modern single-page application.

The project achieved recognition (winning first prize in the Telegram Lightweight Client Contest) and serves as the code base behind the official web client available at web.telegram.org/a. The architecture takes advantage of advanced browser capabilities: WebSockets for real-time messaging, Web Workers and WebAssembly for performance-critical tasks, multi-level caching and PWA features for offline or near-offline usability, voice recording and media streaming, raw binary data handling and cryptographic operations. It also handles rich UI/UX elements such as CSS/Canvas/SVG animations, reactive data streams, etc. -

Nexus Messenger
All your messaging apps in one window, one session per account.
Nexus is a desktop hub for Windows that keeps the web apps you use all day in one window, pinned to a sidebar and one keyboard shortcut away. What sets it apart is session isolation. A browser only holds one WhatsApp Web session at a time: opening a second account signs the first one out. Teams is no better, and Microsoft's own answer is to use another browser. Nexus gives every service its own isolated session, so two WhatsApp numbers and two Teams organisations stay signed in at once. It also does the ordinary things well: native Windows notifications with per-service mute, unread badges in the sidebar, taskbar and tray, a catalogue of common services plus any custom URL, drag-and-drop ordering, and per-service sleep to give memory back. Nexus tracks the stable Electron line, which decides whether those services keep working: they drop support for old browser engines twice a year. Free, open source under the MIT licence. English, French and Spanish. -
24
Altus

Altus includes a built-in dark mode and a theme customizer for changing interface colors. Advanced users can also create custom CSS themes. System tray integration allows the application to continue receiving notifications while minimized. -

Answer Overflow
Powering Discord content discovery by making web pages from threads
Answer Overflow is an open-source project that turns Discord help channels into searchable web pages.

It can index questions, organize solved discussions, provide analytics, and surface insights about common problems and helpful contributors. Large technical communities can use it to transform repeated Discord answers into long-term public knowledge. It is especially useful for developer tools, open-source projects, and support-heavy servers that rely on Discord as a primary help channel.
